You can't start investing in start-ups and expect to hit the good ones without excellent access and knowledge. You will almost certainly lose all your money. Invest in the S&P 500 using an index fund, that's it. Investing in the S&P 500 is another way of investing in "the world's economy", and that will, hopefully, go up over time. And if it goes down, then at least you're not the only one who lost money so your money will be worth as much as it used to anyways.
